Great product! - Midwest Industries MP5 Optic Picatinny Top Rail

This item provides great height from my vortex red dot, no more extremely low iron sights to struggle to look through. However, this product is pretty hard to install. It took me about 40 mins to master how this should be put on and screwed down. I found that on my MAC 5, the welds were not perfect, so I had to adjust how I was screwing it down to get the mount level, but after figuring out that it can be worked with to make it perfect, it is a great product because of the ability to adjust it.
